为了更好地利用木质素、提高木质素的吸附功能，对木质素及其提取方法进行了详细阐述，并综述了将木质素制备成吸附剂的相关技术及其应用领域。低共熔溶剂提取法较好，且具有绿色环保、低成本、高效的优点。通过化学反应改变木质素的结构或添加活化剂来提高木质素的吸附性，具有潜在的研究价值。

In order to make better use of lignin, the adsorption function of lignin needs to be improved.Lignin and its extraction methods are described in detail.The related technical methods for preparing lignin into adsorbent and the application fields of lignin adsorbent are summarized.It is judged that the deep eutectic solvent extraction method is better than other preparation methods, and has the advantages such as environmental friendship, low cost and high efficiency.It is of potential research value that the adsorption of lignin is improved through changing its structure by chemical reaction or adding activator.
